Introduction to Hematology: Characteristics and Functions of Blood
- Hematology is the study of blood and blood-forming tissues, including their formation, function, and associated diseases.
- Blood is composed of plasma and cellular elements, including leukocytes, platelets, and erythrocytes.
- Plasma makes up approximately 55% of the blood volume, while erythrocytes make up 45%, and leukocytes and platelets make up 1%.
- The principal component of plasma is water, which contains various dissolved ions, proteins, carbohydrates, fats, hormones, vitamins, and enzymes.
- The main protein constituent of plasma is albumin, which acts as a carrier molecule for compounds such as bilirubin and heme.
- Other blood proteins carry vitamins, minerals, and lipids, while immunoglobulins and complements are involved in immune defense.
- Erythrocytes contain hemoglobin, which is responsible for transporting oxygen and carbon dioxide between the lungs and body tissues.
- Leukocytes defend the body against foreign antigens, such as bacteria and viruses.
- Platelets are necessary for maintaining hemostasis.
- Blood comprises 8% of the body weight, with a volume of 4-5 L in females and 5-6 L in males.
- The temperature of blood is 37-38°C, with a pH of 7.35-7.45 and a viscosity of 4.5-5.5 relative to water.
- Blood is composed of plasma (90% water and 10% other substances) and formed elements (red blood cells, white blood cells, and platelets), with plasma containing various proteins such as albumin, globulins, and fibrinogen.
Erythrocyte: Formation, Maturation, and Membrane
- Erythrocyte refers to the formation of red blood cells, which have a circulating lifespan of approximately 120 ± 10 days.
- Erythroid progenitor cells begin with hematopoietic stem cells (HSC) and differentiate into committed erythroid progenitor cells, consisting of burst-forming unit-erythroid(BFU-E) and colony-forming unit-erythroid(CFU-E).
- The process of erythroid maturing cells formation includes six morphologically defined stages: Basophilic Normoblast, Polychromatic Normoblast, Orthochromatic Normoblast, Reticulocyte, and Erythrocyte.
- Normoblasts spend from 5 to 7 days in the proliferating and maturing compartment of the bone marrow, and after reaching the reticulocyte stage, there is an additional 2-3 days of maturation before it is released to the peripheral blood.
- Reticulocytes are immature RBCs that do not contain a nucleus but contain residual ribosomal RNA and remain in the bone marrow for 1-2 days before being released into circulation.
- Erythrocytes are flat biconcave discs, non-nucleated, have a diameter of 7-8 µm, and a flexible structure. Females have 4.8 million erythrocytes, while males have 5.5 million erythrocytes.
- Erythropoietin (EPO) is the only cytokine important in regulating the final stages of erythroid maturation, and androgen appears to stimulate EPO secretion.
- Erythropoiesis is stimulated by Erythropoietin hormone produced by the kidney in response to hypoxia, which can be caused by low RBC count (anemia), hemorrhage, high altitude, exercise, prolonged heart failure, and lung disease.
- The erythrocyte membrane is a phospholipid bilayer-protein complex composed of 52% protein, 40% lipid, and 8% carbohydrate.
- The erythrocyte membrane has two types of proteins: integral and peripheral. Integral proteins include transport proteins and glycophorins, while peripheral proteins include spectrin and ankyrin, which serve as skeletal support for the membrane lipid bilayer.
- The deformability of the red cell is due to its biconcave shape, the viscosity of hemoglobin, and the viscoelastic properties of erythrocyte membrane.
- The function of the RBC membrane is to maintain erythrocyte's biconcave shape, provide deformability, elasticity, permeability, and contain blood group antigens.

- Haematopoiesis takes place in hematopoietic organs, primarily in bone marrow in adults.
- The process of haematopoiesis involves careful balance between cellular proliferation, differentiation, and cell death.
- Hematopoietic precursor cells are divided into three cellular compartments: stem cells, progenitor cells, and maturing cells.
- Stem cells are pluripotential and give rise to all lineages of blood cells.
- Progenitor cells have restricted development potential and include colony-forming units (CFUs) that produce different types of blood cells.
- Maturing cells constitute more than 95% of total hematopoietic cells and are morphologically recognizable.

- Leukocytes defend the body against foreign antigens such as bacteria and viruses.
- Platelets are necessary for maintaining hemostasis.
- Whole blood is bright dark red, comprises 8% of body weight, and has a volume of 4-5 L in females and 5-6 L in males, with a temperature of 37-38ï‚°C and pH of 7.35-7.45.
- Plasma is the liquid part of blood, comprising 90% water and 10% other substances, including plasma proteins (albumin, globulins, fibrinogen) and inorganic substances (Na, K, HCO3, Ca).
- The functions of blood include transporting oxygen, nutrients, hormones, and waste products; maintaining normal acid-base balance, body temperature, and water balance; delivering specialized cells for tissue protection; and preventing leakage by closing holes in blood vessels.
Introduction to Hematology: Characteristics and Functions of Blood
- Hematology is the study of blood and blood-forming tissues, including their formation, function, and associated diseases.
- Blood is composed of plasma and cellular elements, including leukocytes, platelets, and erythrocytes.
- Plasma comprises approximately 55% of the blood volume, while erythrocytes comprise 45%, and leukocytes and platelets comprise 1%.
- The principal component of plasma is water, which contains ions, proteins, carbohydrates, fats, hormones, vitamins, and enzymes necessary for normal cell function.
- The main protein constituent of plasma is albumin, which acts as a carrier molecule for compounds such as bilirubin and heme.
- Immunoglobulins and complements are specialized blood proteins involved in immune defense, while coagulation proteins maintain normal hemostasis.
- Erythrocytes contain hemoglobin, which is responsible for transporting oxygen and carbon dioxide between the lungs and body tissues.

Overview of Leukocyte Development and Function
- Leukocytes develop from pluripotential stem cells in the bone marrow.
- Hematopoietic growth factors influence stem cells to mature into terminally differentiated cells.
- Leukocytes circulate in the peripheral blood for only a few hours before migrating to the tissues.
- Leukocytes serve as defenders of the body against foreign invaders.
- Hematopoietic cells differentiate into stem cells, progenitor cells, precursor cells, and mature cells.
- Myelopoiesis is the process of granulocytic cell differentiation.
- There are five types of human leukocytes: neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
- Neutrophils are the majority of circulatory leukocytes and have a segmented nucleus with two to four lobes.
- Eosinophils have a concentration in peripheral blood from 1-3% and are associated with allergic reactions, parasite infection, and chronic inflammation.
- Basophils constitute from 0-1% of the total leukocyte and function as mediators of inflammatory responses, especially those of hypersensitivity and allergic reactions.
- Monocytes are the largest cells in the peripheral blood and function as phagocytes.
- Lymphocytes generally classified as large and mature lymphocyte and account between 20-40% function of lymphocyte.
Erythrocyte: Formation, Maturation, and Membrane
- Erythrocyte refers to the formation of red blood cells, which have a circulating lifespan of approximately 120 ± 10 days.
- Erythroid progenitor cells begin with hematopoietic stem cells (HSC) and differentiate into committed erythroid progenitor cells, consisting of burst-forming unit-erythroid(BFU-E) and colony-forming unit-erythroid(CFU-E).
- The process of erythroid maturing cells formation includes six morphologically defined stages: Basophilic Normoblast, Polychromatic Normoblast, Orthochromatic Normoblast, Reticulocyte, and Erythrocyte.
- Normoblasts spend from 5 to 7 days in the proliferating and maturing compartment of the bone marrow, and after reaching the reticulocyte stage, there is an additional 2-3 days of maturation before it is released to the peripheral blood.
- Reticulocytes are immature RBCs that do not contain a nucleus but contain residual ribosomal RNA and remain in the bone marrow for 1-2 days before being released into circulation.
- Erythrocytes are flat biconcave discs, non-nucleated, have a diameter of 7-8 µm, and a flexible structure. Females have 4.8 million erythrocytes, while males have 5.5 million erythrocytes.
- Erythropoietin (EPO) is the only cytokine important in regulating the final stages of erythroid maturation, and androgen appears to stimulate EPO secretion.
- Erythropoiesis is stimulated by Erythropoietin hormone produced by the kidney in response to hypoxia, which can be caused by low RBC count (anemia), hemorrhage, high altitude, exercise, prolonged heart failure, and lung disease.
- The erythrocyte membrane is a phospholipid bilayer-protein complex composed of 52% protein, 40% lipid, and 8% carbohydrate.
- The erythrocyte membrane has two types of proteins: integral and peripheral. Integral proteins include transport proteins and glycophorins, while peripheral proteins include spectrin and ankyrin, which serve as skeletal support for the membrane lipid bilayer.
- The deformability of the red cell is due to its biconcave shape, the viscosity of hemoglobin, and the viscoelastic properties of erythrocyte membrane.
- The function of the RBC membrane is to maintain erythrocyte's biconcave shape, provide deformability, elasticity, permeability, and contain blood group antigens.
Haematopoiesis: The Process of Blood Cell Production
- Haematopoiesis is the production of different types of blood cells.
- This process depends on the proliferation of precursor cells that retain mitotic capability and is regulated by cytokines.
- The replacement of circulating mature blood cells depends on the function of hematopoietic precursor cells.
- There are three types of hematopoiesis: erythropoiesis, leukopoiesis, and thrombopoiesis.
- Haematopoiesis takes place in hematopoietic organs, primarily in bone marrow in adults.
- The process of haematopoiesis involves careful balance between cellular proliferation, differentiation, and cell death.
- Hematopoietic precursor cells are divided into three cellular compartments: stem cells, progenitor cells, and maturing cells.
- Stem cells are pluripotential and give rise to all lineages of blood cells.
- Progenitor cells have restricted development potential and include colony-forming units (CFUs) that produce different types of blood cells.
- Maturing cells constitute more than 95% of total hematopoietic cells and are morphologically recognizable.
- Hematopoietic precursor cell survival, self-renewal, proliferation, and differentiation are regulated by hematopoietic growth factors or cytokines.
- The hematopoietic microenvironment, which includes stromal cells and extracellular matrix, is crucial for the development of hematopoietic cells.

- Coxsackie A, Coxsackie B, and echoviruses are non-polio enteroviruses that can cause mild to severe illnesses in people, especially those with weak immune systems.
- Enteroviruses spread through the fecal-oral route and can cause hand, foot, and mouth disease, myocarditis, meningitis, and pancreatitis.
- Poliovirus is a rare paralytic illness caused by a virus that infects nerve cells in the spinal cord, brain stem, or motor cortex.
- Poliovirus transmission occurs mainly through the feces of infected people, and symptoms include fever, headache, and sore throat.
- The immune response to poliovirus includes an initial IgM response followed by IgG, which helps prevent re-infection.
- There are two forms of poliovirus vaccine: live attenuated (OPV) and inactivated (IPV).
- OPV induces blood and mucosal immune response against all three serotypes of poliovirus and is safe and effective.
- IPV is administered through injection and induces a stronger protective immune response than OPV, but it is more expensive and requires qualified health workers and sterile equipment.
- The lab diagnosis of poliovirus can be done through electron microscope, cell culture, or PCR, and serology can be useful in determining if a patient has paralytic poliomyelitis.
- Vaccine-derived polioviruses and rare cases of vaccine-associated paralytic polio are potential disadvantages of poliovirus vaccination.
